Retail Sales Not Bad In November 2013

Written by

Retail sales were up according to US Census. Our analysis was mixed, but it is important to note that the inflation adjusted 3 month rolling average growth is accelerating.

Econintersect Analysis:

  • unadjusted sales rate of growth decelerated 0.3% month-over-month, and up 4.3% year-over-year.
  • unadjusted sales 3 month moving year-over-year average decayed from 4.3% to 4.1% (note that inflation adjusted averages growth accelerated).
  • unadjusted sales (but inflation adjusted) up 4.0% year-over-year
  • backward revisions were up moderately;
  • motor vehicles were the largest contributor to the gain this month, whilst gas stations and miscellaneous retail were the drag on growth.

U.S. Census Headlines:

  • seasonally adjusted sales up 0.7% month-over-month, up 4.7% year-over-year
  • the market was expecting between +0.6% to +0.9% month-over-month seasonally adjusted sales increase (versus the 0.7% reported)

Inflation adjusted retail sales now appears to have an upward trend channel for most of 2013. This month, the data is at the higher end of the range. Retail sales per capita seems to be in a tight range since 2012 – and is consistent with 21st century expansion.

Year-over-Year Change – Per Capita Seasonally Adjusted Retail Sales

From the U.S. Census Bureau press release:

The U.S. Census Bureau announced today that advance estimates of U.S. retail and food services sales for November, adjusted for seasonal variation and holiday and trading-day differences, but not for price changes, were $432.3 billion, an increase of 0.7 percent (±0.5%) from the previous month, and 4.7 percent (±0.7%) above November 2012. Total sales for the September through November 2013 period were up 4.1 percent (±0.5%) from the same period a year ago. The September to October 2013 percent change was revised from +0.4 percent (±0.5%)* to +0.6 percent (±0.3%).

Retail trade sales were up 0.6 percent (±0.5%) from October 2013, and 4.6 percent (±0.7%) above last year. Auto and other motor vehicle dealers were up 10.9 percent (±2.1%) from November of 2012 and nonstore retailers were up 9.4 percent (±2.1%) from last year.

It is obvious from the above graphic that motor vehicle sales much of the time do not track overall retail sales.

The differences between the headlines and Econintersect are due to different approaches to seasonal adjustment (see caveats at the end of this post). Long and medium term trends always agree comparing the adjusted to the unadjusted data – it is the short term trends and month-over-month change where the conflict occurs.

Declines of short duration often occur in the seasonally adjusted series without a recession resulting.

Using employment as a gauge to check growth, employment in retail has been growing at a slower rate than sales growth in the last 12 months.

And finally, as retail sales can be a component of determining a recession start date, the zero line of the graph below could be an indicator a recession was underway (or about to begin).

Caveats On Advance Retail Sales

This data release is based on estimates. However, the estimates have proven to be fairly accurate although tend to miss at economic turning points. Therefore up to three months are subject to backward revisions, although normally slight, can sometimes be modest.

The data in this series is not inflation adjusted – and Econintersect adjusts using CPI less shelter CUSR0000SA0L2. The St. Louis Fed also inflation adjusts the Census seasonally adjusted data. The last two recessions began as the inflation adjusted retail sales crossed the zero growth line.

As in most US Census reports, Econintersect does not agree with the seasonal adjustment methodology used and provides an alternate analysis. The issue is that the exceptionally large recession and subsequent economic roller coaster has caused data distortions that become exaggerated when the seasonal adjustment methodology uses more than one year’s worth of data. Further, Econintersect believes there is a New Normal seasonality. Using data prior to the end of the recession for seasonal analysis could provide the wrong conclusion.

The impact of the monthly retail sales data on GDP is not straight forward. Real GDP (of which the consumer is over 60%) is adjusted for inflation. Further, GDP is an analysis of quarter-over-quarter or year-over-year growth, while retail sales is a monthly data series.

Econintersect determines the month-over-month change by subtracting the current month’s year-over-year change from the previous month’s year-over-year change. This is the best of the bad options available to determine month-over-month trends – as the preferred methodology would be to use multi-year data (but the New Normal effects and the Great Recession distort historical data).

  1. steve, i see youre adjusting for inflation using all items less shelter, which is a good start, but you’re still adjusting sales of automobiles, clothing and furniture with an index that includes airline fares, medical services and tuition…i propose that retail sales be adjusted for inflation by taking each business group and adjusting it with the appropriate CPI component index….i tried it in October and got lucky; it hit real PCE right on the nose…
    down at the end of this post: where it says “We Find Real Retail Sales Rose .75% in October”
    last weeks Incomes and Outlays for October had real durable goods PCE up .8% and non-durables PCE up .7%…

  2. since i’m not sure if my emailed comment made it, the point is that we want to know real retail sales in order to frontrun the BEA’s reports on PCE and GDP…goods are about 1/3 of PCE, which is near 70% of GDP…with the revisions to October in this report, we can calculate that October PCE will see an upward revision that will put real growth in durables and non-durables near a 12% annualized rate…when the November CPI release comes out this week, we can closely approximate the real durables and non-durables PCE for November three weeks before it’s released….bottom line: this report suggests that most early estimates of 4th quarter GDP will have to be revised upward…
